PREPARATION (ref. Figure 1)
Before Use
1. Verify that the product and application are compatible, if in doubt contact Hein-Werner technical service.
2. Before use, read the operator's manual completely and familiarize yourself thoroughly with the product, its components
and recognize the potential hazards associated with its use.
3. Insert handle into handle fork. Tighten bolt on handle fork to prevent accidental removal of handle while in use.
WARNING: Do not lift or carry jack by handle. Handle could dislodge and jack fall, resulting in possible injury
or property damage.
4. To familiarize yourself with the basic operation of the jack, locate and turn the release valve (handle):
a. Clockwise until rm resistance is felt to further turning. This is the ‘CLOSED’ release valve position used when
raising the load.
b. Counter-clockwise, but no more than 1/2 full turn from the closed position. This is the ‘OPEN’ release valve
position used to lower the load.
5. With saddle fully lowered, and release valve closed, pump the operating handle. If lift arm responds immediately,
jack is ready for use. If jack does not respond, follow Bleeding/Venting Trapped Air procedure below.
6. Jack should roll freely. Raise and lower the unloaded saddle throughout the lift range before putting into service to
ensure the pump and release valve operate smoothly.
7. Replace worn or damaged parts and assemblies with Hein-Werner Replacement Parts only. Lubricate as instructed
in Maintenance Section.
Bleeding/Venting Trapped Air
With the Release Valve in the OPEN position (4b above) and Saddle fully lowered, locate and remove the Oil Filler
Screw. Pump Handle 6 to 8 full strokes. This will help release any pressurized air which may be trapped within the
reservoir. Check oil level and reinstall Oil Filler Screw.

! WARNING
OPERATION
Lifting
WARNING: Lift only on areas of the vehicle as specied by the vehicle manufacturer.
1. Follow the vehicle manufacturer’s recommended guidelines for lifting. Engage the emergency brake and chock
each unlifted wheel in both directions to prevent inadvertent vehicle movement.
2. Locate and close the release valve by turning the handle clockwise until rm resistance is felt.
3. Refer to the vehicle manufacturer owner’s manual to locate approved lifting points on the vehicle. Center jack
saddle under lift point.
4. Verify lift point then use handle pump to contact lift point. To lift, pump handle until load reaches desired height.
5. Transfer the load to appropriately rated jack stands.
WARNING: Never work on, under or around a load supported only by a hydraulic jack.
WARNING: Overloading may cause hydraulic system failure and sudden loss of load.
Lowering
WARNING: Clear all tools and personnel before lowering vehicle. The further release valve (handle) is turned
counter-clockwise, the faster the load will descend. Maintain control of the speed at which the load lowers at
all times.
1. Raise load high enough to clear the jack stands.
2. Remove jack stands, carefully.
3. Slowly turn the release valve (handle) counter-clockwise, but no more than 1/2 full turn. If the load fails to lower:
a. Use another jack to raise the vehicle high enough to reinstall jack stands.
b. Remove the malfunctioning jack and then repeat steps 1 and 2 to remove the jack stands.
c. Using the functioning jack, lower the vehicle.
4. After removing jack from under the load, push saddle down to reduce ram exposure to rust and contamination.

MAINTENANCE
NOTICE: Use only quality grade hydraulic jack oil. Avoid mixing different types of uid and NEVER use brake uid,
turbine oil, transmission uid, motor oil or glycerin. Improper uid can cause failure of the jack and the potential for
sudden and immediate loss of load. Hein-Werner hydraulic jack oil HW93291 or equivalent is recommended.
Adding oil
1. Lower saddle fully.
2. Set jack in its upright, level position.
3. Locate and remove air vent screw.
4. Fill with hydraulic uid until slightly above the inner cylinder as seen from the air vent screw hole.
5. Reinstall the air vent screw.
Changing oil
For best performance and longest life, completely replace hydraulic uid at least once a year.
1. Lower saddle fully.
2. Remove the air vent screw.
3. Lay the jack on its side and drain the uid into a suitable container.
NOTICE: Dispose of hydraulic uid in accordance with local environmental regulations.
4. Fill with hydraulic uid until slightly above the inner cylinder as seen from the air vent screw hole.
5. Reinstall the air vent screw.
Lubrication
A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that wheels,
casters and pump assemblies move freely.
Cleaning
Periodically check pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth
.
NOTICE: Never use sandpaper or abrasive material on these surfaces.
Storage
Lower the saddle to its lowest position when not in use.
REPLACEMENT PARTS (ref. pages 6 & 7)
